The epidural space runs from the top of your spine to your coccyx. Nerves travel through the epidural space as they travel from your spinal cord to your body.
An injection of steroids (usually mixed with local anaesthetic) can help treat pain arising from damaged nerves. Nerves can be damaged around the spine usually due to inter-vertebral disc disease or degenerative spinal disease. This can produce pain, which we call Radicular Pain or Sciatica. Epidural injections target these nerves as they travel through the epidural space.
Depending on where your pain is your Pain Medicine Consultants may inject either via the Caudal canal (near your coccyx) or via the lumbar spine. If your pain is occurring in the neck or arms your specialist will inject into the cervical spine.
